The Sun Fire V890 Server Service Manual provides detailed procedures that describe the removal, installation, and replacement of serviceable parts and options in the Sun FireTM V890 server. This service manual also includes information about diagnostics and maintenance of the system. This book is written for technicians, system administrators, qualified Sun service providers, and advanced computer system end users who have experience troubleshooting and replacing server hardware.

This manual presents information in a modular format designed to answer the type of questions that you might ask while servicing the Sun Fire V890 server. Typically, the modules cover specific tasks for a service-related procedure for a specific component.

Service providers who would like more general information about the system should refer to the appropriate chapter or section in the Sun Fire V890 Server Owner's Guide.

How This Book Is Organized

The chapters in this manual contain a series of related service tasks. Using the table of contents or the task list on the first page of each chapter, you can quickly find the procedure you need to perform a specific task. The procedures for the tasks are brief; however, they are interrelated and often refer to other modules in the book. For instance, the procedure "How to Remove the Motherboard" is related to many tasks covered by other modules. You must perform these requisite tasks before or after replacing the motherboard.

This book is divided into seven chapters and six appendixes.
